[Septic shock with multiple organ failure after returning from Southeast Asia]. / Choc septique avec défaillance multiviscérale au retour d'Asie du Sud-Est.

For a patient recently returned from a tropical country in intensive care, the leading hypothesis for a fever leading to multiple organ failure is evidently malaria. Nonetheless, many other causes are possible and should be considered: parasites, viruses, and bacteria. A multidisciplinary discussion between specialists in emergency medicine, radiology, pathology, and infectious diseases is essential to start appropriate treatment as quickly as possible without impairing the patient's prognosis.

[Acute liver failure and severe exertional heat stroke: uneasy management in Africa]. / Coup de chaleur d'exercice grave et insuffisance hépatique aiguë: difficultés de prise en charge outre-mer.

Exertional heat stroke (EHS) is a medical emergency defined as tissue injury secondary to a prolonged period of extreme hyperthemia during strenuous physical activity. In the vast majority of cases, EHS is associated with minimal liver involvement with no clinical manifestations. However acute hepatic insufficiency has been reported including a few cases treated by liver transplantation but with poor results suggesting that conservative management is preferable. The purpose of this report is to describe a patient who developed EHS with acute liver insufficiency and multiple organ failure in Djibouti. Despite the remote location and limited medical resources available, full recovery was achieved with conservative therapy and intensive care.

[Management of transdermal therapeutics in perioperative care]. / Gestion des thérapeutiques transdermiques en anesthésie.

OBJECTIVE: To provide guidance on perioperative management of most frequently encountered transdermal therapeutics in anaesthesiology: nicotine, fentanyl, nitroglycerin, scopolamine and estradiol. DATA SOURCES: A review of the last decade literature was carried out on the Pubmed database using the following keywords (transcutaneous or percutaneous or transdermal or transdermic or skin or dermal) and (drug delivery systems or therapeutic systems or drug administration) grouped under the Mesh terms cutaneous administration, perioperative care, surgery, pharmacokinetics, nicotine, fentanyl, nitroglycerin, scopolamine, estradiol. STUDY SELECTION: Original articles, general articles reviews, guidelines, letters to the editor and case reports have been selected. DATA EXTRACTION: Articles were analyzed for each transdermal treatment in terms of pharmacokinetics as well as anaesthetics and surgical interactions. DATA SYNTHESIS: Transdermal nicotine must be removed before anaesthesia of patients with coronary disease or with high risk of inhalation and in case of reconstructive surgery. Transdermal fentanyl must be maintained during the perioperative period and associated with preventive treatments of hyperalgesia. Transdermal administration of fentanyl by iontophoresis is a promising system for postoperative analgesia. Transdermal nitroglycerin must be maintained before scheduled surgery of a coronary patient. Transdermal scopolamine must be removed the day before surgery because of its side effects. It could have an interest in the prevention of postoperative nausea and vomiting, but its therapeutic method remain to be defined. Transdermal estradiol can be maintained during the perioperative period. CONCLUSION: The management of transdermal therapeutics in peri operative care can be adapted for each treatment and for each patient by knowing pharmacokinetics as well as anaesthetics and surgical interactions. In emergency situations, the actions to be taken do not generally differ, but one must be aware that the effects of trandermal treatments do not disappear immediately when removed, due to their pharmacokinetics properties.

[Diabetic ketoacidosis with a fatal issue: is it a MODY3 (maturity-onset diabetes of the young type 3)?]. / Acidocétose diabétique d'évolution fatale: serait-ce un MODY3 (maturity-onset diabetes of the young de type 3)?

Ketoacidotic coma is one of the possible diabetes mellitus first symptoms. It results from complete or relative lack of insuline and is often associated with type 1 diabetes. The authors report a case of a 45-years old woman with inaugural diabetes of which atypical features have motivated the study of MODY gene (maturity-onset diabetes of the young). Gly574ser polymorphism in the HNF-1alpha gene was found, in homozygous state, and the question of the responsibility of this polymorphism in this diabete is asked.

[The myxoedema coma exists, we met it]. / Le coma myxoedémateux existe, nous l'avons rencontré

The myxoedema coma corresponds to the ultimate evolution of a hypothyroidism and is characterized by a major deficit in thyroid hormones responsible for a collapse of the metabolism. The preventive and curative treatment is based on the administration of thyroid hormones, whose benefits are opposed to the cardiovascular risks related to an iatrogenic hyperthyroidism for patients often old with cardiopathy. We report the case of a 92-year-old patient with unbalanced hypothyroidism and chronic cardiac deficiency, who presented a myxoedema coma in the postoperative period of an urgent digestive surgery. This observation illustrates the difficulties in treating patients with unbalanced hypothyroidism following emergency surgery, in the absence of consensus on the type and the amounts of thyroid hormones substitution.

[Intravenous ketoprofen for severe lithium-induced polyuria]. / Traitement par kétoprofène intraveineux d'une polyurie sévère survenue au cours d'une intoxication au lithium.

INTRODUCTION: Although lithium has a narrow therapeutic range, it is widely used in psychiatry because of its antipsychotic and antidepressant properties. During long-term treatment, the onset of nephrogenic diabetes insipidus is common, but few cases of severe hypotonic polyuria, which would be an aggravating factor, have been reported. Appropriate treatment in such cases is an open question. CASE: We report a case of acute lithium poisoning in a 42-year-old man, due to chronic lithium treatment (plasma lithium=2.6 mmol/L). This patient, admitted to our intensive care unit, presented neurological disorders complicated by the early emergence of severe nephrogenic diabetes insipidus. After perfusion of hypotonic solution and intravenous treatment with ketoprofen (100 mg x 3/24 h), the polyuria improved rapidly. COMMENTS: The beneficial action of nonsteroidal antiinflammatory drugs lies in their capacity to inhibit prostaglandin synthesis. Lithium causes excess production of prostaglandins, which decrease the ability of kidneys to reabsorb free water. Some publications report indomethacin to be effective in this case. Because it is available only in oral or rectal forms, however, its effect may be delayed. Our case suggests that intravenous ketoprofen, with its rapid onset of action, is effective in the treatment of severe lithium-induced nephrogenic diabetes insipidus. Rehydration must be strictly monitored because of the risk of renal failure connected with nonsteroidal antiinflammatory drugs.
